DOOR BUFFER.

Specification of Letters Patent.

Patented Jan. 1'7, 1922.

Application filed January 3, 1921. Serial No. 434,437.

To all whom it may concern:

Be it known that LSETH B. A'rwooo, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented new and useful Improvements in Door Buffers, of which. the following is a specification. v

This invention relates to door buffers, and while capable of general application, a buffer in accordance with my present invention is particularly adaptable for use on automobile bodies.

One of the primary purposes of my invention is to provide a buffer which can be made economically of sheet metal, and which can be readily applied to the door jamb by simpl sliding it into a socket provided there or by drilling a circular hole of shallow depth into the face of the door jamb.

Another object of the invention is to rovide a buffer, the metal body of which w en installed on a door, will completely cover the space or opening surrounding the same, resulting from the circular contour of the socket in which the rectangular buffer body is disposed.

A further object is to manufacture the buffer body from a single piece of sheet metal, which, when stamped and pressed in accordance with. my im roved method, forms a body of'the requisite size and contour adapted to receive the 'rubber. bufi'er' which maybe slipped into place in the undercut socket or groove provided in the metal body portion.

advantages-of'this invention will be readily appreciated asthe same, becomes understood by reference to the followingdescription when considered in connection with the accompanying drawings.

Referring to the drawings:

Fig. 1 is. a plan view of the metal blank from which my improved bufl'e'r body is formed;

Fig. 2 is a face view of the bodyme'mher after the stamping operation;

Fig. 3 is an edge view of the partially formed body shown in Fig- 2;

Fig. 4 is a view similarto Fig. 2, showing the body after the expanding operation;

Other objects and many of the attendant.

Fig. 5 is anedge view of the body formed as shown in Fig. 4.;

Fig. 6 is a face view showing the application of the buffer to a door amb;

Fig. 7 is an edge view of the same; and

Fig. 8 is a sectional view onzthe line 8 of Fig. 6.

In the practice of my method, by which my novel buffer is produced, a piece of sheet metal is first stamped out into the shape shown in Fig. 1, forming a flat blank. 11 of metal, having rounded rear corners 12, and tangs or projections 13 at the forward corners, which, as will be apparent from Fig. 1, are tapered at their inner edges from their bases toward their outer ends. The same operation which stamps out the metal blank also forms a countersunk screw hole 14, positioned as illustrated.

This blank is then subjected to the operation of a pair ofdies which depress the central portion of the blank forming a socket 16, in the center of which is disposed the screw hole 14, the socket having straight side walls 17 and a straight rear wall 18, all asshown in Fig. 3. The tangs 13. are

also by the same operation bent downwardly at the front edge of the body, as will be apparent from FigsJ 2 and 3.

The next step is to provide undercut side walls for the socket 16 by expanding the lower portions thereof. This is accomplished by-insertingendwise into the socket from the front end thereof, a tool, the sidesof which are inclined so that the side walls 17 are forced outwardlyat their lower ends into the position indicated in Figs. 4 and 5. When thus positioned, the inclined inner edges of the tangs 13 lie flush with the inner faces jamb, thereby eliminating the chiseling and incident labor and expense necessary'to produce a rectangular socket, such as is customarily necessary for the reception of buffers of this general type. The round socket is produced by simply boring a shallow hole into the face of the-door jamb, the center of the hole bein coincident with the center of the screw ho e 14 whenthe metal body portion of the buffer is positioned in the socket. It will be observed from Fig. 6 that the socket is so disposed that it is intersected by the shoulder 23 of the door jamb, this are being of a proximately the width of the socket 16 of t e buffer body, so that by breaking out a small portion of the wood wall to conform to the inclination of the walls 17, the body' may be slid into position in the socket from right to left, viewing Fig.

6. It will be observed that the rear cor-' ners of the socket 16 engage at two points with the perimeter of the socket 22 and that the flange 21 overlies and completely covers the annular (portions of the socket 22 which are notfille by the metal body.

When the body has been slipped into position, as describedya screw 24 is. inserted through the screw hole 14 and screwed into the door jamb.l9, thus securelyfastening the body in. position. TheI 'rubber buffer ortion25, which consists of a rubber block having inclined side walls conforming tothe inclination of the. walls 17 of the metal socket, is then slipped into position'from the open end of this socket so that its outer edge projects beyond the metal of the body,.as shown in Figs. 6 and 8' in position to be engaged by the flange or rib 26 of the door 27 when the door is in closed position, as shown in Fig. 8. Thisbuiferblock, which is im serted into the metal body under a slight compression, will be retained in position by its resiliency.

It will be apparent that I have provided a door buffer, the body rtion of which is composed of a single piece of sheet metal stamped to shape so that itprovides an undercut socket for the reception of the rubber buffer block, also provides a marginal flange which enables the body to be used in a circular socket, thus obviating the necessity of cutting out a rectangular socket in the door jamb. Furthermore, the tangs or lips which are bent down at the forward edge of the body, form a metal face at each Sl(6 of the buffer block which covers the rough edges of the socket formed in the wooden jamb, and gives a finished appearance to the completed buffer.

It is believed that the construction of a door bufl'er embodying my invention and the method of producing the same will be unbod derstood from the foregoing without further description, and it should be also manifest that the structural details of the buffer face and at one end to receive a buffer block.
